cultivating device properly with relation to the char actor of the ground and the condition of the soil.

A further object of the invention is to provide means f'or enabling the plow beams to be readily adjusted lat- 0 (-rally of the cultivator to arrange the same to suit the various widths of rows of corn.

Another object of the invention is to provide means for enabling the cultivator to be readily guided, either to the right or left to avoid hills or rats and to over- 5 come the side draft or strain, resulting from the unevenness of the ground. a

The invention also has for its object to provide :rcultivator of this character in which the main inuno of the machine willbe adjustable backwo'rdly and forwardly 0 with relation to the axles to enable the machineto beadjusted to suit the size or weight of the driver, so that the machine will be properly balanced.

hinging the upper terminals of the hanger rods, which connect the arch supporting frames with the front of the main frame. Fig. 9 is a detail view, illustrating the manner ol' slidably connecting the tops of the arches with the main or supporting frame. a

Like numerals of reference designate corresponding parts in all the figures of the drawings.

The main or supporting frame of the machine is composed of front and reantransversc bars 1 and ,2 and side bars 3, suitably secured at their ends to the termi nals of the front and rear transverse bars. The rear transverse bar 2 is constructed of angle iron, or other flanged metal, and consists of a vertical flange and a horizontal flange 4, which constitutes a track or guide for a pair of arch supporting frames 5.

The side bars3 are provided with transverse perio- .rations 6, arranged at intervals and adapted to receive bolts 7 for adjustably securing bearings 8 tothe outer edges of the side bars. The bearings 8 receivevertically projecting pivots 9 of axles 10, and are adjustable backwardly and forwardly to arrange the main frame properly with relation to-the axles to suit the size or weight of the driver, so that the machine will be properly balanced when in use. The upwardly extending pivots 9 of the axles are secured in the bearings 8 by keys, or other suitable fastening devices.

The spindles oi the axles 10 receive carrying wheels 11 and are provided with inwardly extending arms 12, which are connected at their inner'ends with'a centrally arranged transversely disposed lever 13. The transverse lever 13, which is located at the rear portion of the main frame of the cultivator, is pivoted by a bolt 14 to a central longitudinal connecting bar onmember 15 of the main frame. The central connecting bar or member 15, which is suitably secured to the front and rear transverse bars oi the main frame, constitutes a arms of the axles, and are adapted to oscillate the same when the rear transverse lever 13 is swung on its pivot.

The rear transverse lever 13 is connected at opposite sides of its center to the rear end of a pair of flexible connections, consisting of chains 18, extending forwardly from the said transverse lever to a pair of pulleys or sheaves 19, and depending therefrom The pulleys orshe'aves,f which form guides for the chains 18, are suitably mounted at opposite sides of a bracket 20, and thedepending ends of the chains 19 are connected to a pair 01" foot levers 21, which are arranged at an inclination, as clearly illustrated in Fig. 4 of the drawings, and which are pivotally connected at their front ends 22 to the front transverse bar 10f the main irame. 'lhe foot levers have their rear terminals located within rigid portion of the latter andbraces the same at the the main frame, and the foot levers are adapted to be.

depressed for oscillating the rear transverse levor 13.

' When the transverse lever is swung in one direction,

the wheels will be swung toward one side of the cultivator, and when'the rear lever 13 is moved in the opposite direction, the wheels will be swung towardsthe opposite side of the cultivator.

By this construction the cultivator may be readily turned to either side and may be easily guided to clear ruts, hills, obstructions and the like, The front ends 22 are pivoted by bolts, or other suitable fastening devices 'to depending ears of substantially L-shaped plates or brackets 25, which are suitably secured to the front transverse bar of the main frame.

The arch supporting frames 5, which are located at opposite sides of the center of the cultivator, each consists of apair of inclined sides or bars and a transverse connecting bar or portion 26, located at the rear transverse bar 2 of the main frame and slidabl y connected with the same by means of substantially L -shaped plates or pieces 27 and rollers 28. The L-shaped plates or pieces 27 are suitably secured to the transverse bar or portion 26 of the arch supporting frames, and extend upwardly and rearwardly therefrom and form a pair of rearwardly projecting lugs, which pro jcct over the horizontal flange of the rear transverse bar 2. The rollers 23, which are located beneath the horizontal flange of the rear transverse bar, are in practiceheld against the same by the draft, which results in an upward pressure on the inclined arch supporting frames 5, and the said rollers or wheels form anti-friction devices and reduce the friction and enable the arch supporting frames to be easily moved transversely of the cultivator to move the plow beams 29 inwardly and outwardly to arrange thesame to suit the width of rows of the corn.

The arch supporting frame is provided at opposite sides with laterally extending bars or members, consisting of angularlydisposed rear portions 30 and front portions, which are arranged in substantial parallelinn with the sides of the arch supporting frames 5. The inclined sides of the arch supporting frames 5 e);-

tcnd downwardly and forwardly from the rear portion of the main frame, and they are connected with the front portion of the main frame by means of hanger rods 31, hinged at their upper ends at 32 t0 the front tmnsverse bar of theniain frame, and pivotally or hingedly connected at their lower ends 33 to the front ends of the laterally ext ending bars or members 30 of the arch sup porting frame. I The lower ends of the hanger rods are provided with eyes, which are linked into perforations of the front ends ofthe bars 30, hilt any other form of hinge orpi jvot may be employed. The upper ends of the inclines. sides of the arch supporting frames are conand the front ends 35' of the rods 34 are bent downward at an angle to form vertical pivots, which pierce the front transverse bar ofthe main frame. The rear ortions of the arch supporting frames looscl y receive or engage the horizontal flange of the rear transverse bar 2 of the main frame, and there is sufficient play of the parts to enable the arch supporting frames to 'be' readily moved laterally of-- the cultivator the'desired' distarice to suit the width of rows of the corn.

The plow beams, which may be constructed in any desired manner, and which may be provided with any preferred form of cultivating blade or shovel, are provided at their front ends with suitable perforations for the reception of laterally extending pivots 36 of arches 37, which are composed of vertical sides and .a connecting top portion. The pivots 36, which extend outward from the sides of the arches 37, pierce the lower ends of the inclined sides 5 and the outer portions of the laterally projecting braces or members 30, and the plow beams are adapted to swing upwardly and downwardly on thesaid pivots. Thetops of the arches are slidably connected with the main or supporting frame by guides 37, consisting preferably of metallic straps and secured to and depending from the draft bars or beams. The guides, which are adapted to prevent the arches from swingingbackwardly or forwardly in the bearings of the arch supporting frames, and the laterally extending bars or members thereof prevent the arches moving transversely of the I achine. The arches are connected by rods 38 with forwardly and rearwardlyprojecting arms of a substantially T- shaped lever 39, which has a laterzilly projecting arm The rods 38 are provided at their outer endswith eyes 4], which embrace the inner sides of the arches at the upper ends thereof, but the rods may be connectod with the arches in any other desired manner. The T shaped lever'is located beneath the central 10ngitudinal bar 15 of the main frame, and is pivotally connected with the same by a bolt 42, which pierces the center of the T-shapedlever. The laterally ert tending arm 40 of the T-shaped lever is connected by arod 43 with a short operating lever 44, fulcrumed at an intermediate point ona bracket 15, which is pro vided with a toothed segment 46. The lower arm of the operating lever 44 is connected to the rear end of the rods 43, and the upper arm of the leveris provided a toothed segment 50, which is adapted to be engaged" by a spring actuated dog or deteht 5] of a central operating lever 5 2. The central operating lever 52 is hired to the-continuous transverseshaft, and is adapted to raise and lower the plow beams simultaneously as hereinafter eirplsined, 'lhe'transVcrs shaft 48 also supports inner and outer side levers 53 and 54. The inner levcrs 53, which are loosely mounted on and adapted to swing independently of the continuous transverse shaft 48, are provided at their lower ends with forward y projecting arms Sound the outer lcrcrs' 54, which are also capable of movement independently ofthe continuous transverse shaft 48, are copnected with forwardly projecting arms '6 by sleeves 57 The gnged by. spring v rigid with the continuousshaft 48. .The side levers are located within easy reach of the driver tho'arms .55 of the inner levers being'locnted above the' plow beams, which areconne cted withtheinncr sides of the arches.

' between the plow beams, and thenrms 56 ere conforated cars 62' through .which the lowcrends-oi the nected with the outer beams. The 'said arms 55 and 56 are preferably connected with the plow beams by means of rods 60, having springs 61, which ere adapted to yieldably hold the cultivating devices in the ground. v

The rods 60'are pivotelly connected with the arm's 55 and 56,;md the plow beams are provided withperrods 60 pass. 'l hesprings 61, which are disposed on the rods, engage the ears ,(52, and'are thereby adapted to exert e1 downward pressure on the plow beams, when the latter are in engagem cut with the'fsoil;
